    • Report Summary 

      Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1988)
      This report contains the results of work completed during the sixth year of the Full Waveform Acoustic Logging Consortium in the Earth Resources Laboratory at M.LT. Over the last six years, our work have evolved from ...

    • Ultrasonic Laboratory Study of Full Waveform Acoustic Logs in Boreholes with Fractures 

      Toksoz, M. N.; Guler, Fatih (Massachusetts Institute of Technology. Earth Resources Laboratory, 1987)
      A set of ultrasonic experiments was carried out to determine the effects of horizontal and vertical fractures on full waveform acoustic logs. Boreholes of 1 cm diameter were drilled in aluminum blocks. Measurements were ...

    • A Method of Measuring Acoustic Wave Attenuation in the Laboratory 

      Tang, X. M.; Toksoz, M. N.; Tarif, P. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1987)
      The measurement of attenuation is performed by directly determining the attenuation operator (or the impulse response of the medium) in the time domain. In this way, it is possible to separate the attenuation operator ...
